Electrode materials for solid oxide fuel cells with proton-conducting electrolyte based on CaZrO3

The work studies chemical stability and thermal compatibility of composite electrodes in contact with proton electrolyte based on calcium zirconate. Composite of electrolytes of CaZr0.95Sc0.05O3-delta and CaZr0.9Y0.1O3-delta with Fe, Ni, Cu, and Pd metals and also with the perovskite oxide of SrTi0.8Fe0.2O3-delta are considered. Temperature dependences of resistance of porous electrodes made of these materials are studied.
